Hi please try CTRL+F5 to refresh the editor and try again,it seem the cache issue

Hi please help to check the Network, check the API result  at my side all works good

In the desktop app pressing, ctrl+F5 didn't change anything. Network doesn't show any error either.  Also, is this related to PDF export not being properly displayed in adobe reader with connections/wires and components missing (edge views the PDF with any error)? 

please try to set PC DNS as 8.8.8.8 and then try again, we are trying to solve this without changing DNS

Hi please click XHR to filter the connection, and then update the PCB, find out the API name "searchByIdAndPre" 

I am getting the same problem as well

Found the component which caused the error for me: C845413 [https://lcsc\.com/product\-detail/Linear\-Voltage\-Regulators\-LDO\_TF\-78L06\_C845413\.html](https://lcsc.com/product-detail/Linear-Voltage-Regulators-LDO_TF-78L06_C845413.html)<br> <br> 

@daveprue @xenons Hi Issue comfired, we will fix it ASAP thank you

@usersupport Changing DNS has no effect. A very old version of desktop is works.

I have confirmed that LCSC Part Number C2683408 caused my problem.  After removing this part, I am able to update pcb.

It seems to be fixed now.  Thank you for your prompt attention to this problem.

@daveprue In my case, the error continues. How did you identify the problematic component? I have a board of 432 components (68 items) - it's hard for me to sort through everything.

@faeton Have you tried cleaning the cache?

@f33net @xenons @f33net Hi， current method 1，Open the schematic, and save as a new project 2, and then via Design - Update Component from Library, update all parts 3, and then you can update to PCB or Convert to PCB we are solving this issue, it need some time

@usersupport It looks like everything is working normally now and no additional actions are required. Thank you very much for the quick solution of the problem. Chinese guys are great, smart and hardworking! You can be trusted!
